Patent number: 5918655Abstract: A view-through cellular window covering includes a plurality of cells arranged parallel to one another. Each cell has at least one side, and a joint unites adjacent sides of each cell. The adjacent sides of each cell are pivotable about the joint such that each cell is variably adjustable between a collapsed position and an opened position. A first cord includes a plurality of elements positioned there along, and each of the elements is engaged to or otherwise attached to one of the upper sides of a corresponding one of the plurality of cells. A second cord includes a plurality of members positioned there along, and each of the members is engaged to or otherwise attached to one of the lower sides of a corresponding one of the plurality of cells. By longitudinally moving the cords, the plurality of cells can be adjusted between the collapsed position, where adjacent cells are separated, and the opened positioned, where adjacent cells contact one another.Type: GrantFiled: March 17, 1998Date of Patent: July 6, 1999Assignee: Comfortex CorporationInventor: John A.

Patent number: 5002112Abstract: Manual deployment apparatus for specialty, pleated or multi-cellular window covering treatments including uniquely hinged mounting rails and single and/or continuous strand pull cords. The invention consists of apparatus that is used to acquire two modes of pleated or multi-cellular shade fabric deployment over generally curvilinear window openings, but particularly over window openings having circular and segmented shapes. A translational deployment, known as the "Blossom Mode" moves as culptured shade from its rest positon by actuation of a continuous cord that is under constant tension. The shade may be deployed to any extent from the mere movement from the completely stowed position to the fully extended. The second modality, known as the "Fan Mode" contemplates deployment of the multi-cellular shade by commencing with the stowed shade marginally secured between a pair of superimposed, and hingably connected rails.Type: GrantFiled: October 13, 1989Date of Patent: March 26, 1991Assignee: Comfortex CorporationInventors: John T.

Patent number: 4984617Abstract: A window covering (10) having the appearance of a pleated curtain of the expansible-collapsible type and containing therein, and discretely postured within at least one plane of cells, an array of slats (30) capable of arcuate movement by a cord ladder (18, 19, 22) apparatus. The preferred embodiment of the invention (10) uses a multicellular curtain of the pleated type (14), and especially one having a continuous web-like ligature connecting the internal acute vertices of the cells. A Venetian blind apparatus is interposed between the outside pleated faces of the cell network so that a blind slat (30) may be rotated from a rest position on one cell ligament (28) and into contact with an adjoining cell ligament (31). Through an array of reflectively coated or opacified slats (26) or ligaments (28), in combination with the rotatable Venetian blind slats (30), light diffusing through the curtain (14) is readily controlled.Type: GrantFiled: November 2, 1989Date of Patent: January 15, 1991Assignee: Comfortex CorporationInventor: John A.

Patent number: 4984432Abstract: An Ericsson cycle machine is disclosed which can be used for refrigeration, liquefaction of nitrogen or as an engine. The invention includes a liquid ring compressor linked to a liquid ring expander by a gas loop that includes a recuperator. As a refrigeration unit, the liquid ring in the compressor is channeled through a heat exchanger to reject waste heat and liquid is tapped from the expander liquid ring and used as a refrigerant.Type: GrantFiled: October 20, 1989Date of Patent: January 15, 1991Inventor: John A.

Patent number: 4958496Abstract: The invention relates to an apparatus for mean pressure control of a Stirling engine without the need for a compressor. The invention includes a multi-tank system in which there is at least one high pressure level tank and one low pressure level tank wherein gas flows through a maximum pressure and supply line from the engine to the high pressure tank when a first valve is opened until the maximum pressure of the engine drops below that of the high pressure tank opening an inlet regulator to permit gas flow from the engine to the low pressure tank. When gas flows toward the engine it flows through the minimum pressure supply line 2 when a second valve is opened from the low pressure tank until the tank reaches the engine's minimum pressure level at which time the outlet regulator opens permitting gas to be supplied from the high pressure tank to the engine. Check valves between the two tanks prevent any backflow of gas from occurring.Type: GrantFiled: January 4, 1990Date of Patent: September 25, 1990Assignee: Mechanical Technology IncorporatedInventor: John A. Corey

Patent number: 4945969Abstract: An extensible and collapsible covering (10) for framed openings. A shade, having periodically emplaced elastic rod stiffeners (28), is motivated over parallel tracks (20) by a movable sill (26). During shade manufacture, stiffeners (26) are inserted into shade pockets by a machine (100) which examines the fabric, excises flaws and creates pockets for the envelopment therein of the stiffeners. The process for flaw removal uses a single pass technique that cuts fabric around a stiffener, reforms it and bonds the cut ends so as to capture the stiffener in a pocket formed thereby.Type: GrantFiled: October 6, 1988Date of Patent: August 7, 1990Assignee: Comfortex CorporationInventors: John T. Schnebly, Thomas J. Marusak, John A. Corey

The invention consists of apparatus that is used to acquire two modes of pleated or multi-cellular shade fabric deployment over generally curvillinear window openings, but particularly over window openings having circular and segmented shapes.

The shade may be deployed to any extent from the mere movement from the completely stowed position to the fully extended. The second modality, known as the "Fan Mode" contemplates deployment of the multi-cellular shade by commencing with the stowed shade marginally secured between a pair of superimposed, and hingably connected rails.Type: GrantFiled: August 17, 1989Date of Patent: June 19, 1990Assignee: Comfortex CorporationInventors: John T.
